Application med May e2,

To all whom it may concern: i

. Be it known that I, HARRY WV. NEUDECK, a citizen of the United States, residing at Fort Dodge, in the county of 7Webster andv provide improved means for attaching the device to a vehicle. It is a further object of my invention to provide the novel combination and arrangement of parts set forth in the following description and claim and inthe accompanying drawings, in which- Figure 1 is a top plan of the invention;

Fig. 2 is a side elevation;

Fig. 3 is a detail rear elevational Vview of part of the machine; and Y AFig. 4 is a detail perspective view of the means employed for mounting the drag boards 19.

Like numerals designate like parts in each of the several views.

lteferring to the accompanying drawings, I provide spaced dragboards or blades 19 and 19', of which there are two sets. Attached to the rear of each of these members 19 and 19' are collars or socket plates 18, adapted to receive the ends 29 of members V17 and 17', which latter membersin turn are pivotally attached tothe downwardly turned claws 9 and 9' of frame members 8 and 8' Y and beam 30 which together' lconstitute the frame work to which the surfacing blades are attached.V As illustrated in Fig. 1, the frame members 8 are somewhat shorter than the frame members 8', and the blades 19 and 19' are accordingly disposed in slanting arceivea pin 31 by which the device may bel attached to the drawbar of a tractor, or to a suitable wheeled frame.

To permit of adjusting blades 19 and 19',

I provide a suitable hand lever 13, opera-- tively connected with segment 12 mounted on a segment beam 11 which is suitably mounted on the outer claws 9 and 9', as shown in Fig. 2 by l pivot-s 10, which cornneet members17 and 17' with claws 9 and 9', respectively. The lower end of lever 13 1s pivotally attached at 14 tothe movable beam 15, which is swung forward ork backward to regulate the position of blades '19 and 19' bythe operation of the lever 13, which isa hand operated lever of conventional type, having a spring and plungerengaging the segment 12 and adaptedto fbe 1 .'65

disengaged therefrom to swing the lever.

To raise and lower the blades for the de- Specication of Letters Patent..A API'. 1922. 1920. serial No. 383,485.

sired depth of cut, I provide a suitable lug 22 on beam 30, to Which is adjustablyV attached one end of rod 24 by a suitable swivel meml ber 32, the other end of rod 24 being atnected with egment 27, both members 25 and 27 being suitably `mounted on the-frame y tached to a suitable lever 25 operatively con# l,

of the tractor or other vehicle to which the I machine is attached. I provide a spring 28, attached to rod 24 as shown or abutting against collars on rod 24. Adjustably mounted in the end of rod- 24 is a suitablebolt 23 which abuts against lug, 22 as rod 24 is drawn forward by lever 25, thus raisingv the frame to which vthe blades of the machine are attached. In operating' the de-f vice in the reverse direction the rod 24 :sov

slides back throughswivel member 32 in which it is slidably mounted andthe spring 28 is compressed. Y v

It is within the kcontemplation of my invention to attach the foregoing mechanismV either to a tractor or to such awheelframe -v as is illustrated in Figs. 1 and 2, comprising the U shaped frame 1 attached toaXle 2 on which are mounted wheels 3, and hav,--

ing a small'truck 5 mounted on beam 4 as'` f illustrated in Fig. 1. I providea Asuitable clevis or hook 6 bywhich theframe is attached to a team. f

In operation the earth taken up by one set ofv plates 19 and 19 is gradually moved over onto the other overlapping set of like plates and thus worked toward the middle rof the road. 1 rIheblades may be adjusted to the most desirable position for surfacingM the road by Y'operating levers 13 and 15V to control'the Vangle and the height, respectively, .Y

of the surfacing plates as .above described. The main beams areiso mounted as to have flexibility both up and down-.and sideways; and may be attached tothe wheeled frame illustrated, vor to a shaft which in turn is attached to thedraw barpof ,a tractor. What I claim is: Y In a road surfacing machine, thecombinaada tion of spaced and parallel sets of glantingly A for adjustably Controlling the angle of the postloned road surfacing plates hzlvlng the road surfacing plates relatlve to the frame adjacent ends of said plates positioned in ol' the machine, tml-means for raising and 10 spaced ovellappmg relatlon, frames on the lowering` the plates vert1cally lndepenclent said plates on which said plates are mounted, of the :ingle at which they are. operated.

said frames being pivotally attached to the bed-y of the road surfaoing machine, means HARRY W. NEUDECK.
